ExploreLearning: Translations

http://www.explorelearning.com/index.cfm?method=cResource.dspView&ResourceID=201

Use the Translations gizmo from ExploreLearning to translate a point or a figure, both vertically and horizontally. This tool offers sliders to translate the figure, as well as measuring tools for measuring lengths and angles.

NLVM: Transformations (Reflection)

http://nlvm.usu.edu/en/nav/topic_t_3.html

Investigate the concept of Reflection by creating custom shape patterns and dragging and turning the line of reflection. Add new objects to the work area to further explore reflection.

NLVM: Transformations (Rotation)

http://nlvm.usu.edu/en/nav/topic_t_3.html

This manipulative allows users to create a custom shape pattern (or use the one provided) and then rotate it around a center point. Drag the black dot located on the line to rotate the object. Drag the black dot that appears at the center of the angle (it will appear when you hover over it) to change the Center of Rotation. The angle of the rotation is provided.

NLVM: Transformations (Translation)

http://nlvm.usu.edu/en/nav/topic_t_3.html

This manipulative allows the user to create patterns using the different shapes provided, and then by dragging the pointed end of the arrow, the user should notice that their pattern moves, but only its location moves -- it doesn't not flip or rotate.

Shodor Interactive: Transmographer

Quickly create a square, triangle, or parallelogram and use the tools to provide to Translate, Reflect, and Rotate your object.

Shodor Interactive: Transmographer 2

http://www.shodor.org/interactivate/activities/TransmographerTwo/

Explore the concepts of Transformations, Reflection, and Rotation with this applet. Create a polygon with the desired number of vertices, and change the ordered pairs around to create different shapes for the polygon. Then choose between the different types of transformations to see the effect it has upon the graphed polygon.
